N2 - The processing of semantic information is pivotal in language cognition. However, there is a scarcity of research exploring the semantic-related patterns associated with aperiodic and transient periodic brain activities. In this study, recently developed algorithms were employed to parameterize the time-frequency characteristics of neural activities captured with optically pumped magnetometers-based wearable Magnetoencephalography from participants engaged in a Chinese semantic-based task. This study elucidated the neural mechanisms during semantic processing, in relation to transient oscillations and aperiodic activity. Additionally, the results demonstrated that these parameterized features could serve as indicators for decoding semantics. These findings may offer novel contribution to analyzing the mechanism of semantic perception, which will be potential to rehabilitation of language disorders with OPM-MEG.
